Application-filed `May 13, 1916, SerialNo. 97,441.

To all' ifi/0m 'may conce/1%.'

Be it known that l, Louis A.. FnnnDMAN, a citizen of the United States., and a resident of the city, county, and State olf New Yorin (whose post-cnice address is 135 l/Vest '536th Street, in said city,) have invented a certain new and useful improvement in Dry-Battery Machines, oi' which the Afollowing is a specification.

Throughout the various views ofthe drawings. similar reference characters designate similar parts. l

The machine 1, set forth in this application, is composed of number of mechanisms for assembling the parts of a dry battery, and knally ejecting the complete cells.

The first, which is designated generically by 'the character 2, places a cup or cell casing 3 in a conveyor fi.

rlhe second mechanism 5 places a suitable disk 6' of insulating material in the bottom of the cup 3.

The third mechanism places a solution 3 in the cup 3 and the next mechanism 9, removes the surplus solution after the carbon bobbin or core 10, has been put in place by hand, or otherwise. as desired.

Thereafter, the conveyor d is passed downwardly by suitable mechanism 11 into a tanlr 12, where the liquid part of the cell is cooked, and thereby solidiiies into a thick paste, and therait'ter, the conveyor l is raised and then lowered and passed into a' Cooling mechanism 13 vand from 'there the conveyor passesto the ejectiug mechanism 1.4L. These various mechanisms are suitably mounted on the frame 15 and driven by the main shaft 16, as will appear below.

Mechanism for placing the @am in the 00n- @cg/01.

The mechanism 2 for placing the cups in the conveyor isvmounted at front of the `machine and composed of va series of inclined slideways 17, nine being shown., each of which parallel with all thev others, and all are supported by means of suitable brackets 18 mounted on the parallel top rails 19 of the frame 15. These inclined slideways 17 are so arranged and disposed that they hold the cylindrical cans or cells 3"'of the batteries so that the cylindrical surface of one is against the cylindrical surface ofl another and the' bottoms are against the bottoms 2O of the slideways 17.

YThe lower end of each slideway 17 is cut away and a spring pressed bolt 21 nori'nally'holds the bottom can 3 in position. This springepressed bolt 21 is thi' st aside by the can whenever a plunger 22 is forced therein by mechanism which will be de scribed below.

At the bottom of each runway is a suit able slideway in each of which is mounted a plunger 22 which has teeth 241 adapted toengage' a'segmental gear 25 mounted on a cross shaft 26 which is supported by suit able bearings 27 from the -rails 19. To permit a proper meshing of the segmental gear FZ5 and teeth 24;, the slideway 23 is suitably slotted and the end of the plunger 2Q, which enters the cup, is provided with a suitable spring-pressed head 23 which is adapted to come in Contact with the bottom of the can, which is engaged, and eject the same from the slideway 17 and put the same in a suitable poclret on the conveyor l which will be described below. i

The shaft 26 is rocked at the right time by means of a suitable crank Q9'which is fined thereon and engages av link 30 which is preferably adjustable as to length, and this link 30 is connected to a mechanism 31 which is driven by the main shaft 16. lt will be understood from. the foregoing that once every revolution of the shaft 16, the plungers 22 are all driven forward and back so as to force the cups which they engage into the conveyor e.

Thel con/vegaa.

The conveyor 4 runs substantially the length of the machine and is in the form of two endless and parallel sprocket chains 32 connected by suitable cross bars 33 each of which is vperforatecil to correspond with the number of cup rows, and provided with suitable spring clip lingers 34 which are adapted to receive the cups. Each fingery 34T is preferably made of a leaf spring having` one end secured at 35 to the bar 33 and adjacent to a perforation tl erein and then this spring extends downwardly and outwardly and then inwardly parallel with the bottom of the can to be received therein and thence upwardly towards the can and then at right angles and parallel to the bottom of the can and thereafter upwardly along the side of the can and finally away from the can so as to flare in the opening of the bar These springs are so arranged and disposed that they will receive and hold the cups as above set forth and hold the same true and yet will not interfere either with the introduction of the cups or their removal.

ln Fig. 1b is shown a clip 34 which is bent substantially as shown and made of spring metal so to rest against the side and botom of the cup which it holds. This form of clip may be substituted forv that shown in 7, if desired.-

Near the cup supplying mechanism 2 mounted a suitable shaft 36 in suitable bea 1ings 37 lhung from the side rails 1S) and near each rail this shaft 36 carries a sprocket-wheel 38 which receives a chain 32. A similar shaft 39 mounted. at the other end of the machine carries corre sponding sprocket wheels (not shown) but identical with the sprocket-wheels 38. This shaft 33 also carries ratchet wheel l0 which is fixed thereon and adapted to enmore or less may be used as desired.

gage two pawls 41 and 42' respectively.y '.l'he pawl 41 is pivotallyy mounted from a. bar 19 in any suitable manner as by a bracket 43 with a pin 44 therein, and the `other pavvl 42 is carried by a. lsuitable arm 45 to which it is pivotally connected at 46. rlhis pawl 42 is also pivotally connected With a suitable link 47 which runs to an eccentric strap 48 which is driven by an eccentric 49 suitably `mounted onl the main shaft 16 of the machine.

Intermediate of` the sprocket Wheels 38 at each end the upper run of the conveyor has other idle sprocket Wheels mounted at convenient distances and also other sprocket Wheels above the chain for depressing the same into the heating tank and the cooler, as will appear below. Guides 126 are also` provided to steady these chains `at the bars carrying cups which are being operated on by the various mechanisnfis of the machine.

ln the preferred embodiment of my invention three springs 34 are employed, although Three have been found to give satisfactory/1 results in actual service.

The cardboard dis/c supplying mechanism.

rl.`he cardboard disk supplying mechanism 5 is composed of magazines 50 which hold disks 6 in parallel columns so that one disk be inserted in each cup; a slide 51 for each reservoir 50 and mechanism for actuating the same and a plunger 52 for forcing each disk into its cup 8 which is also actuated by a mechanism which Will be hereinafter described. ln addition to this, there is preferably employed. an alarm Which Will indicate the absence of a disk from its cup so that the carelessness of an operator will not 'permit the machine to run without supplying sufficient disks.

Each reservoir 50 is composed of a'vertical tube 53 in Which are placed a number of disks 6, one on top 0f another, and these disks are preferably surmounted by a suitable metal weight 54 which presses upon the same and causes them to pass properly through the reservoir. Each slide 51 has a blade 55 which is substantially the thickness of a disk, and no more, and is so mounted that it can pass under the reservoir, and shove the loivermost disk under the plunger 52. Each slide 51 runs in a suitable guide 56, from Which extends upwardly, a suitable bracket 57 at each end and the slide 51 isconnected in each instance to a crank arm 58 through a loose pivot 59 and each crank arm 58 is fixedon a suitable transverse shaft 60 which is driven by a suitable crank 61 from a cam mechanism 62 on the main shaft 16 by means of a suitable link 63 which is preferably adjustable as to length. The cam mechanism 62 is so timed that the `arm 61 vnected, by aloose pivot.

is thrown forward and back once each revolution of the shaft 16 and at the proper time with regard to the other movement of the mechanism herein described. y After a disk 6 has been forced under the plunger 52 by the .slide 51 above described. this plunger 52 descends, under the action of a crank 64, to which it is pivotally con- Each crank 64 is fixed to a suitable sh aft 65 mounted in suit able brackets 66, at each end` and the shaft 65 is driven by a suitable crank 67, which in turn is driven by a link 68 which is connected to a suitable cam mechanism 69 fixed cn the main shaft 16. The link 68 is als@I made adjustable as to length so that the movement of the plunger 52 may take place throughout the proper space required for its action.

The lower end of each plunger 52 is provided with a suitable spring-pressed head 70 (see Figs. 10 and 11) in the center of which in an insulating sleeve so that the needle 71 isfcarefully insulated from the head 70 of the plunger 52. The head 74 presses againsta spring 76,;Which is-connected to an insulated Wire 77 Which runs through -a suitable opening in the `plunger 52 and this Wire 7 7 is provided to a suitable'spring finger 78 Whichis adapted to rub against the plate 79 on the insulation 80 which is fixed to the cylinders 50 Which hold the disks 6. The plate 79 is connected to a suitable Wire 81 Which runs to a binding post 82 supported by 'any suitable insulating means, as a bracket 83, which is mounted onthe upper end of a'tube 80 but insulated therefrom, and this post 82 is electrically connected to a spring armature 84 and also by a Wire 82a with a magnet 85 above the armature 84 se that When the magnet 85 is energized, as will appear below,tlie armaturemay be raised so as to contact with the core of the magnet 85 andvthereby complete a circuitthrough same for a purpose which will appear below. `The Winding of the magnet 85 is connected to a Wire 85EL which runs to a lamp 86 mounted in any suitable Way and at any convenient location, and preferably immediately above the tube 50 for which it is an indicator, as will appear below, and this lamp 86 is connected by a Wire 86L to `a battery 86b which is grounded at 86e to the frame ofthe ma chine. From this it is apparent that when no disk6 is in the bottom of a cup 3 under the lplunger 52 and this plunger descends,

vas above described, the spr-ing pressed insulated'vvire 71 'Will touch the bottom of the and thereby close a circuit which may be fr U llOy

traced from this wire 71 through the wire 72, magnet 85, lamp 86 and battery 86T', andy thence to the ground 86@ so thatl the light 86 will glo-w and the armaturel 84 will be attracted to the core of the magnet 85, and when so attracted a circuit will be closed through. the bracket ed, and thence through` the Wire 85c to a switch 85 and from there to a ground 85 whereby the lamp will glow although no appreciable current will flow through the wire 71 this part of the cir cuit short-circuited. This glow light is an alarm to indicate that the cylinderI underv it has no disk 0 and as soon as the operator restores this disk hc opens the switch 85d mo mcntarily thereby releasing the armature which falls and then the machine will operate in its normal manner, is obvious. The operator is not supposed to open the switch until disks are in place in the cups whichhave been left without disks well as in the cylinder 50 over these cups so that no liquid will be poured into these cups until the same are ready to receive the liquid.

The #lling mechanism.

As the conveyor advances step lby step the cups in a given row, after being supplied with disks, in due season get under' the filling mechanism wherein they are supplied with the cookingpaste necessary to the batteries. This paste flows from a suitable reservoir 87 which is supported by pipes or tubes 88 and through tubes 89 to the measuring mechanism '90, which will be described below. The paste solution is pumped to the reservoir 87 through any suitable means, as a pipe or a tube. The measuring apparatus 90`has a number of tubes each of which is connected to a valve or cock 91. Each of these cocks 91 is actuated by a suitable crank 92 which engages a grooved diskv 98 which is'mounted on a screw shaft 94 which does not turn but shifts in the direction of its length in suitable bearings 95 located near each end. The purpose of making the disks 93 with screw thread perforations going through their centers, is to make them so that they may be adjusted. To securethem in place it is preferable to use suitable locknuts 96. At one end of the shaft 94 is placed a suitable clevis 97 which is connected in a peculiar way to a lever 98 fulcrumed at 99 and connected to suitable link 100, in the usual manner, which is adjustable as to length, the same as the others, and runs to a suitablecam 101 on the main shaft 16 so that at the correct time the respective valves 91 will all be opened and closed. The peculiar way the lever 98 is connected toi'the lnk 100,is as follows: This lever 98 turns free on the pivot 99 and so do the parallel arms 98a which are pivotally connected at their outer ends tothe link 100 by a pivot 98h,

and the parts 98 and 98"" are also connected by latch 98c which is pivotally mounted between the links 9 8a en a pivot 98d. The latch 98c has a foot adapted to engage a shoulder 98C on the lever 98 and its other endL is adapted to engage a set screw 98I mounted in a bracket 98g which is fixed' to the frame of the machine. The latch 98c is connected to the lever 98 a spring 98h so that when the latch 98L is forced clear of the shoulder 98e the spring 98h causes a quick cutoff and closes the valves, almost instantaneously. This action is further facilitated by means of a cushion 94a of rubber or similar material which is held by a bracket 94b so as to be compressed by the end thrust of the rod 94 when. the valves are open.

The valves 91 run to suitable stud pipes 102 which are connected to hand valves or cocks 103 and these in turn run to a second set of stud pipes 104 which have their openings over the cups 3 so that they discharge into the same at the proper time and all discharge at once, the supply being turned off or on all at the same time by means of the mechanism above described. If, for any reason, any pipe is not supplying the cups that come under it, the valve 103 of this pipe is shut off by hand.

The vacuum surplus solution removing mechanism.

After the cups have been filled as above described, they are taken up by the conveyor 4 to the surplus solution removing mechanisni. Between the paste supplying mechanism and the mechanism for removing the surplus paste, lmechanism may be interposed for placing the carbon bobbin cores in the paste. Such mechanism is not shown as it is understood that in the machine herein shown and described, the cores are placed by hand. As these cores vary more or less, as to size and are not of uniform` volume, they displace more or less paste when put in place, and this displacement varies the level of the paste in the lled cups. is this variation in filling is undesirable and wasteful, the surplus removing mechanism 9 is employed to bring all these surfaces to the same level. This surplus removing mecha.- nism consists essentially of a vacuum chamber or suction manifold 105 which is supported by suitable clamps and exhausted by any suitable means, such as a vacuum pump.

This pump and its connections are shown in Fig. 27 where the suction manifold 105 is connected t-o a pipe 105a that runs to a closed receiving` chamber 105b which has a drain pipe 105c running through a valve 105d to a closed storage vessel 105e. The pipe 105a extends tonear the bottom of the vessel 105b and below the liquid level if any amount of liquid accumulates in this vessel and air is exhausted through a pipe 105t which leaves at the top and runs to the bottom olf a second closed safety vessel 105g, and trom the top of this a pipe 105h runs to an exhaust pump 10541 which forces air Atrom the apparatus. This pump run :trom a motor 105j through a belt 105k, or any other suitable means. By disconnecting tho vessel 105e, the surplus liquid may be recovered and later reused, and this may be done at any time Without distnrbii i the exhaust bccause ot the valve 1051 Extending -from the suction mani'folrL are a plurality of flexible suction pipe .0G Which extend to nozzles 114 `which are slidably .mounted in a suitable ci' Ising 113 pivoted in rocker arms 10T suita l;v mounted on a pivot 103, suport-ed by a pedestal 109 secured to a sill 19. It is to be understood that two such pedestals, arms and pipes are employed, one on each side of the machine. The levers 10T are oscillated through a very small arc by means ot a crank 110 and link 1.11 which may'be extended or shortened by a suitable turn-lnicklea and this link 111 gets its proper reciprocation troni a snitable cam mechanism 112 connected to the main shaft 16. The arms 107 are lixed to the pivot 108 so as to oscillate together. The vacuum chamber 105 suitable connections with the filling chaml'ier 87 (not shown) so that the excess paste will flow temporarily into this chamber 105 and later will be placed where it can be used over again Without Waste.

The series of pipes 106 run to suitable nozzles 114, Which are slidably mounted in a suitable crossing- 113 so that they Will move in a vertical direction only when the arms 107 are oscillated. A. parallel movement keeps the pipes 106 ere-ct.

These nozzles 114 have the positions ot their lower ends determined by suitable lock nuts 116 which are pressed against the bar 113 by the tension of suitable coil springs 11.7 so .that each nozzle maybe so placed that it Will be resiliently supported with its lower ends at the proper level. If the core should be out of place or some other obstruction strike the lower end oit a nozzle 114 the nozzle can lift so as to avoid breakage. Under normal conditions, the lower end et each nozzle 114 enters a little below the upper snrface of the liquid or paste and removes the surplus by sucking the same through suitable passages 118 which are preferably placed concentric with central opening 119 ot the nozzle, and this opening 119 is so placed that it will clear the carbon core 10 and its lower end is flared so as to tend to bring the carbon core 10 to a central position if it should be slightly out of true. These nozzles 114 are preferably recessed, as shown 114a to avoid disturbing the liquid which remains in a cup. It Will be understood from the fore'- going that the suction is entirely through the passages 118 andthat the central. opening 119 isnot connected therewith so that the suction'is never' in any Way intertercdvvith by this opening` 110. When the lowerend of the nozzle 114 is no longer below the upper sinitace or" the paste or liquid 3, further suction of liquid becomes impossible as air enters the openings 118, and immediately thereafter the'nozzles 114 are lifted clear of the conveyor and clear ot the `.cup 3 and are in position which will enable them to be lowered at the proper time so that the floregoing cycle of operation may be repeated.l

T716 core centering and preste heating operation.

From the surplus paste removing mechanism the conveyor takes the cans with their contents. one row at a time, under the centering mechanism 11 and into the heating` tank 12.

The centering mechanism consistsy of sprocket Wheels 120 mounted in rpairs on shafts 121, which are liournaled in bearings 122 which are mounted on the sills 19. These sprocket Wheels 120 carry parallel and suitable endless sprocket chains 123 which are uniforn'rwith the chains 32 and are connected at intervals by the centering bars 124 which. are spaced the same as the bars 33 so that the bars 124 will be exactly true and over the cups 3 when the samepass into the headingtank 12. The tapering shaped openinthe bars 124 cause the cores 10 to be properly centered. The edge recesses 124 permit the trapping of any liquid or any disturbance thereof. Suitable sprocket Wheels 1257similar and identical in pitch circle to the Wheels 1207 and mounted on the same axlesi cause the chains 32 to bedepressed when passing` through the heating tank 12. To assure the correct alignment of these chains 32 guides 126 are provided at each side of the tank 12. The liquid such Water) in the tank 12 is su'tlicientlv hot to make the paste harden in the cups 3 and is regulated Lwith a thermostat to control its temperature. The chains 123 run intermit tent-ly, the same as the chains 32 and in due season take the cups 3 out ot the tank 12 at the end ot the proper time required for cooking cells.

The cooling mechanism.

As shown in Fig. 1, the conveyor passes upwardly over idle rollers, after leaving the heating apparatus7 and the Icentering mecha nisni 117 and continues for a moment `at the upper level of the bars 19', and thereafter the chains 32 are depressed by suitable sprocket Wheels 123 mounted on a shaft 129 journaled in suitable bearings 130, as shown. These sprocket Wheels 128 cause the cans with their contents to enter the cooling mechanism 13 Where a cooling liquid such as water is em- "ployed, and a second sprocket Wheel 131 mounted the, same as the sprocket Wheel 128 .on afsvhaft 132 running in journals 133 to The cap ejectz'ag meccanism.

The ejecting meehanisniis shown at the right of Fig, 1a7 and also somewhat in detail in'Figs. 2 and 3. On the inside ot the sills 19 and near the rear ends are located downwardly extending brackets 134, \vhich are united by a crossing 135, which is provided with parallel and vertical perforations which receive the ejeoting plungers 136, each of which is in alignment with a cup 3 and is provided With means described below, for ejecting each cup by raising the saine vertically andy clear of the springs 34 and crossing 33 and level with the table 137 ot the machineA which Will be described beloiv. Each plunger 136 is connect-ed to a suitable crank 138 by means of a loose pivot connection 139, and each crank 138 is lined on an oscilla-ting shaft 140 with its ends mounted in the bracket 134. The shalt 140 is oscillated by means ofa suitable crank and link connection 141 which runs to a suitable cam, not shown, on the main shalt of the inachine.

Another extension of the bracket 134 carries a Shaft 142 on which are mounted a number of) crank arms which are liXed thereto. One of these arms 143 is connected to a suitable coil spring 144 which is secured at its upper end to a fixed part ot the machine andthe upper edge ot a sill 19. This spring 144 is a retract-ive spring); which normally'holds the arm 143 in `the positie` shown. Another arm 145 is lixedly mounted on the shaft 142 and is connected by a loose pivot to alink 146 Which runs to a su itablo cam mechanism 146a on the main shaft 1G, Which causes this link to reciprocate once iu each revolution. Yet another arm, 147 is one of a; pair which runs in a substantially vertical direction to above the level ot the table 137 Where it is attached by links 14.3 to a suitable slide 149 which has fixed therein, a, number of parallel fingers 150 which @liter` corresponding openings in the ends ol? the vertical. division plates 151,

The cams which drive the links 141 and 146 arel sol timed that at the proper time, Whenabar'33 with its cups 3 is under suitable,- perforations 152 in the table 13'?, the p lungers 136y are elevated and thereby caused todift the row of cups 3 above the level of the table137 While the upper ends oit the plun-l gersj 13,61v are abovey the level of the table. and with a sweeping movement oi? the slide ifi-ideen 149 the cups aremoved from over the perforation 152 on to 'the table 137, above described, and before tb e plune'ers are lov/ered, the action ol ie cam driving` the link 146 is such that this link is raised and thereby forces the slide 149 backward 'and the paste chamber has suitable paste, the

empty cans 3 are first loaded into the conveyor 4, above described, ana.. then the dis L G are placed on the bottom thereof, and nerd; the cans are i'illed to the prop ,r level with the paste 8, then the cores 10 are inserted by hand, in the embodiment oi my invention herein shown, althou. n theyv may be inserted by' machine if desired, or otherwise, i then the si nlns paste is removed by the vacuum apparatus above described.

After the paste is ren'ioved the cans are first heated to cook the paste fliile the cores are held in a central position, and then the cans are passed from a heating' to a cooling' device wherein the cans are cooled and the pasto is solidified and made hard., and then the.

cans are passed in the complete form, dulj,T
